1 Scope

This part of YS/T 667 specifies the determination of arsenic, mercury and lead in aluminum hydroxide and pseudo-boehmite for filler. This part applies to the determination of arsenic, mercury and lead in aluminum hydroxide and pseudo-boehmite. Determination of the range. arsenic 5 × 10-5% ~ 5 × 10-3%; mercury 1 x 10-5% to 5 x 10-3%; lead 5 x 10-4% to 5 x 10-3%.

2 principle of the method

The sample is dissolved in hydrochloric acid, and at a certain acidity, the element under test is hydrogenated in the hydride generator to be enriched. And then import Argon plasma source excitation, the spectral determination. To select an effective complexing agent to mask the effect of the matrix and other interfering elements on the assay.

3 reagent

Unless otherwise stated, only deionized water or comparable purity of water is used in the analysis. 3.1 hydrochloric acid 1 + 1 (excellent grade by sub-boiling secondary distillation). 3.2 Arsenic Standard Solution.
